SGT1 is not required for bacterial PAMP-triggered immunity

Show abstract
Plant immune signaling activated by the perception of pathogen-associated molecular patterns (PAMPs) or effector proteins is mediated by PRRs and NLRs, respectively, and often share cellular components and downstream responses. The suppressor of the G2 allele of skp1 (SGT1) is a core immune regulator required for the activation of NLR-mediated immunity. In this work, we examined the requirement of SGT1 for PRR-mediated immune responses in both Nicotiana benthamiana and Arabidopsis. Using complementary genetic approaches, we found that SGT1 is not limiting for early PRR-dependent responses or anti-bacterial immunity. Therefore, we conclude that SGT1 does not play a significant role in bacterial PAMP-triggered immunity.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
